Single-Button Display Mode Switching Using Stored EDID Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users are limited to a single display size and must purchase multiple displays to meet different usage needs, and current display adjustment features require multiple steps, making quick switching between scenarios difficult.
Innovation Solution
A display with a memory, physical switching element, and controller that allows users to switch resolution and screen size with a single button, using candidate extended display identification data stored in the memory and controlled by the controller upon receiving a switching signal from the physical element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users purchase multiple displays of different sizes to meet various usage needs, then the display functionality and versatility are improved, but the device complexity and cost increase
Solution Approach 1:
The patent implements a single display device that can perform multiple display functions by storing multiple Extended Display Identification Data (EDID) sets with different screen sizes and resolutions. The display controller can switch between these different EDID configurations based on user selection, allowing one display to replace multiple specialized displays for different usage scenarios such as gaming, multimedia, and productivity tasks.
2Adaptability or versatility
If current displays provide a Display Mode feature with multiple adjustment steps, then the display adaptability is improved, but the operation complexity and switching time increase
Solution Approach 1:
The patent pre-configures multiple complete EDID data sets in the display memory before operation, each representing a different display configuration optimized for specific scenarios. When the user selects a display mode, the controller directly loads the corresponding pre-prepared EDID data, eliminating the need for multiple sequential adjustment steps and enabling instant switching between different display sizes and resolutions.

AI summary
A display includes: a memory, a physical switching element and a controller. The memory is configured to store multiple pieces of candidate extended display identification data. The physical switching element is configured to be triggered by external force to generate a first switching signal. The controller is connected to the physical switching element and the memory. The controller is configured to control a displayed screen according to original setting data among the pieces of candidate extended display identification data, and adjust the displayed screen according to target data that is different from the original setting data among the pieces of candidate extended display identification data after receiving the first switching signal.
